On August 11, 2026, Quantum Corporation (the “Company”) notified Laura A. Nash that it had determined to transition her from her role as the Company’s Chief Accounting Officer and Principal Accounting Officer effective September 1, 2026. Ms. Nash will continue to serve in her current role until September 1, 2026, and is expected to remain with the Company as a full-time employee in a transition role until December 31, 2026, at which time Ms. Nash’s employment with the Company is expected to terminate. There are no disagreements between the Company and Ms. Nash and no disruption to current operations is expected as a result of this transition.

The Company will continue to pay Ms. Nash’s current base salary, and she will continue to vest in her outstanding equity awards through her transition period. In consideration of Ms. Nash’s agreement to serve in an extended transition role, the Company agreed to accelerate the vesting of approximately 2,900 restricted stock units currently held by Ms. Nash, subject to Ms. Nash continuing to serve until December 31, 2026 and the execution by Ms. Nash of a standard release of claims. In addition, subject to the execution of the standard release of claims and in accordance with the terms of her current employment agreement, the Company will pay Ms. Nash six months of her base salary and six months of COBRA expenses.

The Company anticipates announcing a new Principal Accounting Officer on or around September 1, 2026.
